我目前拥有的代码如下：

ipn.php：（IPN 监听器）
如果上面第二个链接中的框为空，只需单击“重新开始”并单击下一步，直到进入第 4 步，或单击此处：https://www.paypal-labs.com/integrationwizard/adaptive/main。 php

我认为这是启动付款的代码，我需要在此处指定自定义值吗？如果是这样，如何？

原始问题：
我有一些来自贝宝的脚本，允许用户从我的网站付款。
在他们使用基本支付脚本发送付款的第一步中，我得到了这些值：
Array (
[responseEnvelope.timestamp] => 2011-04-08T01:34:03.578-07:00
[responseEnvelope.ack] => Success
[responseEnvelope.correlationId] => a2de97aaf57f0
[responseEnvelope.build] => 1822511
[payKey] => AP-8AW04791DK417062F
[paymentExecStatus] => CREATED )
当从贝宝确认付款时，使用他们的 ipn 系统，我得到这些值：
test_ipn = 1
payment_type = instant
payment_date = 01:11:38 Apr 08, 2011 PDT
payment_status = Completed
address_status = confirmed
payer_status = verified

last_name = Smith
payer_email = buyer@paypalsandbox.com

我看不到任何允许我建立连接的值，允许我更新正确的数据库记录以说明付款已成功完成。
